London Welsh assistant coach Gordon Ross admits his side lacked composure after they threw away a golden opportunity to claim their first win of the 2014/15 campaign.
Despite leading Newport Gwent Dragons by ten points at half-time, tries from Richie Rees and Tom Prydie turned the LV= Cup tie on its head.
The Exiles are rock bottom of the Aviva Premiership Rugby table, have lost all four of their LV= Cup pool matches and have fared little better in Europe.
And Ross says his team must learn to believe in themselves after they failed to get over the line at Rodney Parade.
“The first half was good and we made good decisions behind the scrum and it was frustrating that we did not go another score in front,” he said.
“But fair play to Dragons, they changed their game plan, played a lot tighter and that is what got them the win.
“There has been three games on the bounce now that we have probably had chances to win. Last week [a 20-15 defeat to Saracens] and today we were in positions where we should have probably won.
“They are signs that a team has not won a game with a lack of composure and confidence to get over the finishing line.
“Their spirit and endeavour was excellent but we have to play a bit smarter in key areas.”
Tristan Roberts sailed a penalty between the posts on nine minutes and, after Prydie levelled, the Exiles took control when Nick Scott went over in the corner for the game’s first try. Roberts added the extras.
And despite Nic Reynolds being sent to the bin, Welsh went further in front before half-time with another Roberts penalty.
But Dragons were transformed after the interval and Rees picked a hole in the Welsh defence to score and Prydie duly converted.
Roberts was then shown a yellow card and, with the Aviva Premiership Rugby side on the ropes, Prydie scored a converted try to seal the win.
Dragons’ director of rugby Lyn Jones, a former coach at London Welsh, believes a win will soon come for the long suffering Kassam Stadium faithful.
“I thought London Welsh were good. Their line-out work and possession was tidy and provided lots of possession as their breakdown was,” he said.
“They were always going to struggle at the start of the season with new players and they are getting better and better.
"They are not far away from a victory.”
